General Meaning:

Other Contexts:
* par-dessus: This emphasizes something being placed on top of something else. For example, "put the blanket over the chair" (mettre la couverture par-dessus la chaise).
* au-dessus de: This emphasizes location above something else. For example, "the plane flew over the city" (l'avion a volé au-dessus de la ville).
* fini, terminé: These mean "over" in the sense of finished or completed. For example, "the meeting is over" (la réunion est finie).
It's important to choose the right translation based on the specific context.
